After frequent power cuts in central Mumbai this month, the Brihanmumbai Electricity Supply and Transport (BEST) is finally upgrading its infrastructure and replacing its age-old system.

Sources in the Undertaking said that it is now setting up a new 33 Kv distribution substation that would cater to central Mumbai areas like Sion, Prateeksha Nagar, Dharavi, GTB Nagar, Antop Hill and other surrounding areas.
